Pegoland^® Uno C1

Technical Caracteristics

High-strength cement, selected aggregates and additives product, which contributes to its great workability and strength.

Advantages and Uses

• Adhesion of medium to high absorption level ceramic tiles.
• Suitable for interior and exterior use.

Suitable Substrates

• Conventional cement-base substrates.
• Do not apply on top of paint.
• Substrates must be resistant enough, stable, sound, and clean. Free of dust, release agents, organic products, etc.
• All substrates should have adequate flatness. If this is not the case, make screeds of up to 5 mm with the same product 48 hours before gluing.
• For a greater thickness apply:
  • On bonded screeds: Apply levelling paste NIVELAND 10R or PAVILAND RECRECIDO AUTONIVELANTE depending on the substrate and requirements.
  • On flooring: Use regularization mortars with adequate tensile strength and with a curing shrinkage already completed.
• In case of heavy heat, wind, or very absorbent substrates, it is advisable to moisten the substrate and wait until the water film is totally absorbed.
• In exterior floors, the substrate must have a slope equal or greater than 1%.
• Do not apply on top of gypsum, plaster, anhydrite, or any other substrates with high content of sulphates, or in contact with water or moisten with high content of sulphates.
• All substrates must comply with the specifications outlined in section 6.4 of UNE 138002 standard.

Application Procedure

• Add water and mix manually or mechanically until getting a homogeneous consistence, easy to work with.   Let the paste rest around 5 min. then mix again.
• Spread the kneaded product on the substrate with the help of a trowel on a maximum extension of 2m2.   Comb the area with a notched trowel to level the thickness (Check table).
• Place the tiles on the fresh adhesive, pressing and moving them until getting a complete smashing of the grooves and the proper adhesion of all the ceramic surface. Periodically check the stickiness of the adhesive by lifting a previously laid tile, if the appearance of a film without transfer on the surface of the adhesive or dehydration of the adhesive is observed, proceed to remove the material and apply a new product.
• Laying of tiles by back buttering method outdoors, for tiles with superior to 45 cm side, if levelling systems are used or if the tiles have a relief that may interfere the gluing process.
• Respect the placement joints between tiles as indicated in section 7.7 of UNE 138002 standard. For interior areas the joint width should be ≥ (1.5 - 3) mm, and for exterior areas, the joint width should be ≥ (3 - 5) mm, depending on the type of installation and the larger side of the tile being placed.
• Joints should be refilled after 24 hours in vertical parameters and 48 hours after in pavements.
• Use a suitable MORCEMCOLOR range mortar considering the type of joint.

NOTE: The shorter the time between combing and laying the tile, the better results will be obtained.

Notched-trowel panel

Maximum tiles weight in vertical parameters: 30 kg/m² 

Recommendations

• The successful completion of ceramic installation can only be ensured through careful planning. Therefore, we recommend consulting the current national standards in each country, such as the UNE 138002 standard in Spain, which provides specifications for material selection, proper planning, use, and installation, to achieve the required levels of quality, performance, and durability.
• Do not apply in temperatures below 5ºC or above 35ºC, and avoid application in conditions at risk of frost, rain, intense winds, or direct sunlight. Under extreme weather conditions (high wind or elevated temperatures) drying occurs faster.
• Temperatures, ventilation, absorption of the substrate and coating materials can vary the workability and setting times of the adhesive.
• Never apply with the “by dots” technique.
• Do not apply in areas where there is a risk of stagnant water.
• Respect the movement joints (structural, contraction, expansion, and perimeter joints) as indicated in section 7.8 of UNE 138002 standard. These joints can be addressed by using prefabricated joints or filling them with an elastic sealant from the PUMALASTIC range.

Expansion joint sizing

Sizing of perimeter joints

• Use a PEGOLAND PROFESIONAL range adhesive for gypsum-based substrates, avoid old gypsum or weak plaster.
• For pieces with fibreglass mesh reinforcement glued on the back, consult technical department.
• Pieces that can get stained due to their high-water absorption must be placed with fast-setting adhesives. Use PEGOLAND FAST FLEX C2FTE S1.
